The software is in reverse order with the heaviest Private Working Set usage for idle and scan combined listed first, going down to the lowest score and most efficient. If you want to jump straight to the list of results to see how your antivirus got on, they are at the bottom of page 2. Sophos Endpoint Security and Control Emsisoft Anti-Malware 7.

McAfee AntiVirus Plus Bitdefender Antivirus Free Edition 1. Avira Free Antivirus Number of Processes: 6 Processes Monitored: avgnt. Web Anti-virus 8. Number of Processes: 6 Processes Monitored: dwarkdaemon. This was a fairly comprehensive comparative review of many AV. It addressed more or less the information I was searching for would be nice if CPU usage was included but memory usage gives a fair idea.
I have NOD32 and Malwarebytes on my pc and working very well together. Malwarebytes is very very ligth!
There is no right or wrong, truth or lies in this situation, just opinion, and that user gave their opinion. I ditched BitDefender about a month ago for the same reason. I just read this review for the first time and it impressed me quite a bit. As a geek, I try to stay current, but unless you specify your search to include system usage when looking for the top antivirus, you just get the standard results. This standard result is effectiveness of protection but leaves out system hog reports.
What may well provide the most secure may also lend to system drag. I wish that this type of testing was done on any page that is reporting top Thank you for your had work. Can one have his or her cake and truly eat it too? And this is not on just one PC, but many running XP at office and at home. Of course having a product that does not slow you down is better. Coding is of course a key factor to that extent. Second but also important, ranking AV on the memory is just leaving aside that the best protection is not just the lighter but most of all the one that protects you best!
What the use of a solution that weight nothing but let pass thoushands of threats? Same thing the otherway round, a very heavy solution that blocks even genuine programs will waste your time and patience.
That is why we made it clear at the end of the article that this is one test, to test memory usage, and nothing else. It is not for the best overall, the best detection rates or the fastest, just plain and simple RAM consumption during use.
Hal, that was a very good test. And yes, you did explain it was only based on memory and nothing else. Very plain comment for all to see :. It would be nice to see the summary sorted to memory usage as it is the purpose of this article. Presenting it in alphabetical order is not effective. Good test though. I think that MalwareFox is also worth a mention here, it was consuming about megabytes at idle and something when scanning.
I have Avast and was just wondering once again iff I should renew and get something else.. I love my Avast and hope it remains as it is. I was also thinking this. Dang, I wish I would have renewed Avast. Thanks for all the reviews and testings you did. As I did also when needed a free virusscanner, when noticed the MSdefender was eating lots of recourses, it is become fat in Windows10 64bit. So I did download Avira free and while using this software I also noticed that the memory usage is now being reduced, only this software does cause an hudge memory leakage.
Now I did the same on my sons system only now I did install Panda free, here the same results. The total memeory uses is even more then MSdefender. No drivers or software was intalled afterwards so this is pure caused by the antivirus software of Avira and Panda free. So leaving MS defender does not help when you want to reduce the memeory. I have 8ram installed btw. Malwarebytes is not classed as a full antivirus and is more something you use along with your antivirus software.
Some programs, like Avast and AVG, even idling, do not even let the harddrive usage leds go off anymore. The impact of that is a system that becomes sluggish while scanning, and sometimes during idling [background scans]. A lot can change in three years since this article was posted, I wonder If Webroot is still one of the best memory performers. Had to give that one a misss as it used over MB of ram on idle and slowed browsing to a snails pace. It did catch the bad guys and was a nice package overall but the strain on my single core cpu consigned it to the rubbish bin.
XP is fully compatable with Webroot and it installed a breeze only uses MB of ram too whilst browsing and virtually NO cpu resources. It is. Biggest surprise was Bitdefender paid versions using so much memory MB plus at idle — almost as much as McAfee!
Yet the labs and most reviews praise it as being light. Windows Defender on Win 10 uses about MB at idle. Norton Security 30MB is also lightweight but has more features than I need. That is the reason antivirus such as Panda is lower on memory because most of its work is done in the cloud. This can cause performance issues when scanning or detecting viruses as it keeps having to contact a server while a locally stored database can process much quicker.
So where you gain in one area you might lose in another. As pointed out in the article, higher memory usage does not automatically translate to a worse product, and as the old saying goes, unused memory is wasted memory….
Thanks for the article. Like 8 months ago I made some test myself and came to a similar conclusion. Avast Free has fewer binaries running in the background and are small ones. Most antivirus are like that. Try using them for days without restart usually I just hibernate my computer for faster startup , they will consume hundreds MB of your RAM. But be aware if you finding low mem consuption, you must find alternative which have good virus checking test ;-.
Do they even have a paid review program? No affiliate links too. I can bet you if the list is some other antivirus, there will someone just like you complain about it. I have Eset for our two PC home network. Looking in Task Master with my PC at idle and no apps open. Eset is using 71MB of memory. Definitely a Hog! To be honest, a good antivirus loads its fingerprint database in memory to be able to scan faster. Memory usage for me is less important than detecting a virus before it can do any harm.
In fact, if AV programs store their database in swap, it will slow down your PC overall, and it would allow a virus to do harm before it would be detected. And it does! Sometimes using so much of my resources that my audio completely goes out. The best and lightest free antivirus software is NAS!! Total Security adds a spam filter, a powerful parental control system, and an efficient firewall.
